IMPROVEMENT IN AUTOMATIC FANS.

Specification forming part of Letters Patent No. 123,476, dated February 6, 1872.

SPECIFICATION.

I, WILLIS DE LANCEY HALL, of Memphis, county of Shelby, State of Tennessee, have invented certain Improvements in Automatic Fans, of Which the following is a specification:

My invention relates to an improvement upon an automa-tic fan, patented by me September 26, 1871; and consists in attaching a swivel-ring to the end of standard G, or rod supporting the frame, the clockwork, and ian, reference being had to the accompanyingI draw# ing and to the letters marked thereon, in Which- Figure l is a perspective view of the automatic fan With the adjustable standard of my former patent. Fig. Z is a side elevation of the fan with my improvement attached. Fig. 3 is an end elevation of the fan with the adjustable standard. Fig. et is an enlarged view of the standard or rod with my improvement.

The purpose or' this swivel-end ring is to suspend the machine over a bed, table, or any place Where a current or' air may be desired, so that when in operation a rotary motion is given by reason of the indented shape of the fan-leaves E E E EN.

To enable others skilled in the art to make and use my invention, I r ill proceed to describe its construction and operation.

I construct a semicircular frame, F, in accordance with the desired dimensions of the fan-leaves. This frame is attached to a round standard or rod, G, and to the end R of rod G is attached a swivel-ring, S, of not larger dimension than the rod G, so that the rod or standard G can be used in connection with the standard I K of my former patent. Attached to one side ofthe frame F is the train of clockwork A, with the pinion C, attached to Which is the axle D, running through the diameter of frame F. Attached to this axle D are arms, and attached to these arms are the fan-leaves E E E E". At one end of arm of frame F is a screw, C', binding on one end of axle D. By tightening or loosening the same the mo tion of the fan-leaves can be increased or diminished.

The machine is operated, after rst suspending it by the swi\f'elring over a bed, table, or Wherever desired, by Windin g up the spring of clock Work 5 the axle with theI'an-leaves is thereby made to revolve, causing the desired agitation of the air.

Ol aim The automatic fan, combining the standard G, having the swivel-joint and ring S, With the frame F, supporting the clockwork A, pinion C, and aXle D with the arms or Will gs E E E E", and set-screw C', all constructed and arranged substantially as describfd.
